Definitions

  • the invention relates to lighting devices or signaling for a motor vehicle, according to the preamble of claim 1.
  • a projector for vehicle automobile comprising a support having an orifice threaded, and a position adjustment screw comprising a threaded body received in the orifice of the support by making a screw-nut connection therewith.
  • the screw has a bearing end coming into contact with a surface a part of the vehicle body after assembly of the projector.
  • the adjustment screw receives a clamping screw bearing against one end of operation of the adjusting screw and against the workpiece body to rigidly immobilize the screw together and the body part.
  • the document DE-42 28889-A1 describes a projector of this type.
  • Body thread and port thread are made so as to allow a certain play longitudinal along the axis of the body as well as a certain transverse play perpendicular to the axis when the adjusting screw is received in the hole, for facilitate the operation of the screw.
  • the clearance longitudinal persists and results in longitudinal play along the axis between the projector and the workpiece body.
  • An object of the invention is to provide a lighting or signaling device ensuring immobilization without play along the longitudinal axis of elements connected by the adjusting screw.
  • the reference part in turn requests the screw on the contact area in causing the screw to tilt in rotation by relation to the organ in the orifice from which it is received.
  • This tilting occurs around an axis of rotation perpendicular to the longitudinal axis of the screw.
  • the tilting causes the screw thread to come into abutment against the thread of the orifice, at two points located on either side of the axis, the stops being oriented in directions parallel to the longitudinal axis and opposite each other. This results in cancellation of the longitudinal clearance between the thread of the screw and the thread of the organ. On the vehicle, noise and vibrations.
  • This switchover also removes the game transverse perpendicular to the longitudinal axis by abutment of the adjusting screw against the member or the organ net.
  • the contact zone extends over a corner sector around the lower longitudinal axis 180 °.
  • the contact area is constituted by a point.
  • the reference part requests the screw adjustment at a significant distance from its axis. We obtain so easily the tilting of the screw by means of a even moderate effort.
  • the bearing end present at the minus three points defining a first support plane of the bearing end on a flat surface, this plane being inclined to the direction perpendicular to the axis, the three points delimiting a corner sector around the axis greater than 180 °.
  • the bearing end has a continuous plane face defining the foreground support.
  • the bearing end is constituted by the flat face.
  • the screw has an opposite operating end longitudinally at the bearing end and present at minus three points defining a second support plane of the operating end on a flat surface, this second support plane being substantially parallel to the first support plane, the three points delimiting a angle sector greater than 180 ° around the axis.
  • the adjustment screw is requested, not parallel to its axis, but perpendicular to the second support plane and parallel to the foreground support. We therefore favor the tilting of the screw and its stable hold in the tilted position.
  • the operating end has a continuous planar face defining the second support plan.
  • the adjusting screw has a operating end opposite longitudinally to the support end.
  • the adjusting screw 2 is intended to allow the position adjustment of a signaling device or lighting, in particular of a vehicle headlight 4 automobile relative to a part 6 of the bodywork of the vehicle used as reference.
  • the projector comprises a support 8 comprising a cylindrical conduit 10 tapped by presenting a thread 12 reduced to approximately one tower. This conduit 10 constitutes an orifice for receiving the adjusting screw 2.
  • the adjusting screw 2 has a hollow body of general cylindrical shape with longitudinal axis 5 with a central cavity.
  • the body is threaded on an external face by presenting a thread 14 extending over several rounds.
  • the body thread 14 is adapted to cooperate with the thread 12 of the conduit 10 by making a screw-nut connection.
  • the threads 12, 14, the body and the ducts are dimensioned so that this link household, between the body and the duct, a following longitudinal play axis 5 as well as a transverse play perpendicular to this axis.
  • the body has first and second ends 16 and 17, longitudinally opposite one to the other along axis 5.
  • the first end 16 is constituted by a flat face slightly inclined by relative to a direction perpendicular to axis 5, by example by forming an angle ⁇ of about 30 '.
  • This face 16 extends from the external face of the body to a internal face of the body. It has a general shape annular, is continuous, and covers an angle sector of 360 ° around axis 5.
  • the first end 16 constitutes a support end of the adjusting screw 2. In addition, it defines a first support plane P of this end 16 on a flat surface, this support plane P being inclined with respect to the perpendicular direction to the axis 5.
  • the inclination of the face 16 causes it has a single geometric point 18 extending in forward along the direction of axis 5 with respect to other points on this face.
  • This point 18 constitutes a contact zone between the bearing end 16 and a flat surface perpendicular to axis 5.
  • the body has two flanges 20, 22 of cylindrical shape with axis 4.
  • the collar 22, which we will call internal collar, has an outer face of radius smaller than the radius of an internal face of the collar 20, which we will be called an external flange.
  • the internal collar 22 extends opposite the external flange 20.
  • Each flange has a flat edge 21, 23.
  • the two edges are coplanar and registered in the same plan P ', that we will call the second support plan.
  • This second plan support P ' is parallel to the first support plane P and so tilted similarly to a direction perpendicular to axis 5.
  • the second end 17 is one operating end.
  • Edge 23 of the collar internal 22 has a generally continuous annular shape and extends over a corner sector around axis 5 of 360 °.
  • the edge 23 of the flange internal 22 thus defines the second support plane P 'of the operating end 17 on a flat surface.
  • the operating end 17 is hollow at its center and communicates with the body cavity.
  • Position adjustment screw 2 is associated with a clamping screw 24 comprising a threaded rod 26 and a head 28 having a plane face perpendicular to an axis of the rod and contiguous thereto.
  • the bodywork part 6 has a wall plane which has an orifice 30 of diameter less than diameter of the internal face of the body of the adjusting screw 2 and greater than the overall diameter of the threaded rod 26 of the clamping screw so that it can be passed through this one.
  • a nut 32 is welded to the part 6 against a face thereof intended to be opposite the support 8, in being coaxial with the orifice 30.
  • the bodywork part 6 has a flat face around the orifice 30 and in look at the bearing end 16 of the adjusting screw.
  • the assembly is carried out as follows.
  • the adjusting screw 2 is engaged in the conduit 10 of the support for engaging the two nets 12 and 14 mutual, without deeply pushing the adjusting screw in the conduit. Then install the projector on the vehicle, the conduit 10 coming opposite the orifice 30 of the bodywork part 6, with the axis 5 of the screw adjustment perpendicular to the flat face of this part, the orifice 30 being centered on the axis 5.
  • the mounting of the headlamp 4 on the vehicle is adapted so that the area contact 18 of the adjusting screw 2 comes to rest against the part 6 along the axis 5.
  • the support 8 extends to distance from the workpiece 6.
  • the clamping screw 24 is then installed in the adjusting screw 2, the flat face of the head 28 coming in support against the edge 23 of the operating end 17 with interposition between them of a washer 32.
  • the rod 26 crosses the adjusting screw 2 along the axis 5 and the orifice 30 of the part 6, and comes into engagement with the nut 32 by making a screw-nut connection.
  • the thread 14 of the adjusting screw stresses the thread 12 of the support parallel to the axis 5 in the opposite direction to part 6.
  • the thread 14 of the adjusting screw urges the thread 12 of the support parallel to axis 5 in the direction of room 6. The longitudinal clearance parallel to axis 5 between the screw setting 2 and the support 8 is thus canceled.
  • the thread 14 of the adjusting screw can come into abutment against the thread 12 of the conduit 10 and / or the internal face in the direction perpendicular to axis 5.
  • the game transverse to axis 5 is thus also canceled.
  • the contact area 18 could be a extended surface and not an area reduced to a point.
  • the first support plane P at the support end 16 could be defined by a discontinuous planar surface, even by only three points.
